(BERKELEY, Mo., AP) — Violent protests broke out again in suburban St. Louis after another fatal shooting of a black 18-year-old by a white police officer.

The shooting happened around 11:15 p.m. Tuesday at a convenience store in Berkeley, Missouri, just a few miles from Ferguson, where Michael Brown, an unarmed black 18-year-old, was killed by a white officer in August.

St. Louis County Police Chief Jon Belmar says the Berkeley shooting victim was black and the officer white.

Belmar says police were called about a theft and as the officer questioned two men, one pointed a gun at him. The officer fired three shots. One hit the gunman.

A violent protest broke out. Two officers were injured, police cars were damaged and fire was set at a QuikTrip store. Four people were arrested.
